tles to prevent'the refilling ofthe latter after the withdrawal of v theJoriginal contents.

It has for its object the provision of a device that Vnot only willprevent the refilli ing ofthe bottle, but also lone that will permit aneasy and smooth decanting of the1 separate the ylower end of the uppermember original contents.

It further has A'for its object the provision 1 of a device that will beof vinexpensive con'- struction and of such a desi-gn that it can bepractically manufactured of, glass or simii lar material, and also adevice that can be` adapted to the ordinary bottle-neck with but littlechange in the structure ofthe bottle.

The invention consists -in the novel construction, combina-tion andarrangement lof parts, hereinafter described, pointed outl in theappended claims, Vand illustrated in the accompanying drawings.

In the drawings, in which similar reference characters designatecorresponding parts, Figure 1 is a vertical sectional view of thebottle-neck and the valve-mechanism in place therein. Fig. 2 is asimilar view showing the ybottle-neck inclined for deoanti ing purposes.Fig. 8 lis a vertical sectional view showing a modification. Fig. 4shows perspective views of the different members separated fromeachother.

The bottle-neck 5 is of the ordinary formation, except that in its innerface is the annular groove 6, `the purpose vof which will be explainedfurther on.

The body of VJthe valve-mechanism consists of a cylindrical casingcomprising theupper member 7 and the lower member S. This casing has alongitudinal bore 9 that is concentric with 'the longitudinal axis ofthe bottle-neck when the casing is in place, and this bore forms thepassage for the discharge of the contents of the bottle. On theperiphery of the upper member '7, intermediate of its ends, is thecollar 10; and on the periphery of the lower member 8, adjacent to itsupper end, is the collar 11. These collars tit the interior diameter ofthe vbottlemember.

neck and position the casing within the bottlc-neck.

The two members 7 and S of the casing are united by a screw-threadedconnection. 0n the upper end of the lower member 8 is the threadedprojection 12, which fits a similarly shaped recess in the lower end ofthe upper member. At this joint the two members are cemented together orotherwise firmly united so that the two members will be inseparable. 'Onthe upper end of the lower member 8, below the threaded projection 12,is the annular seat 13. The diameter ofthis seat 13 is slightly greaterthan the threaded 4projection '12 so as 7to slightly ,7 and the top ofthe collar 11 of the lower 0n this annular seat 13 is the flexiblewasher '14 clamped between the collar 11 and the adjacent end of themember 7.

Normally this washer li-es flat against the collar 11 and Vprojectsbeyond the same. 'Vhen the casing is inserted in the neck of the bottle.and shoved into the same, the fiexible washer folds back into the spacebetween the two collars 10 and 11 until it reaches vthe annular groove 6in the inner face of the bottle-neck, into which it springs and locksthe casing in place. After the engagement of the washer with the groove,the casing cannot be withdrawn, for the collar 11 forms a backing forthe washer so that the latter cannot bend downward to clear the groove.The groove 6 is so located that when it is engaged lby the washer thevalve-casing will be so positioned within the bottle-neck as to leaveconsiderable space between its outer end and the mouth of the bottle.

The lower end of the bore 9 is contracted to form the valve-seat 15,adapted to be closed by the globular valve 16. In the bore above thevalve 16 are the balls 17, the weight of which serves to seat the valvein place and also `to prevent access to the valve vfor tamperingpurposes. The valve 16 has a diameter considerably less than that of thebore, so `that the liquid passing through the valve-seat can flowthrough the bore past the valve. The balls 17 have diametersapproximately lthe vsame as that of the bore, so as to be freelymova-ble back and forth therein. In the upper part of the wall of thebore 9 are the longitudinal passages l1S that permit the liquid that hassoV passed the valve 16 to flow past the balls 17 These passages 18extend the length of the upper member 7 of the valve casing, which iscoextensive with the length of travel of the balls within the casing. Onthe inner face of the upper member 7 is the collar 81 flush with theedges of the passages 18. When the bottle is in an upright position, asshown in Fig. 1, the upper ball 17 registers with the collar 81 andthereby closes the bore against the introduction of liquid through themouth of the bottle. Vhen the bottle is in a decanting position theupper ball 17 drops away from the collar 81, as shown in Fig. 2, andopens the passage through the bore.

The upper end of the cylindrical casing is closed by the cap 19, whichlimits the outward movements of the balls 17 and the valve 16. The capis perforated, as at 20, to permit the outflow of the liquid that haspassed through the bore. This cap is screwed onto the casing and iscemented in place to prevent its removal. As the cap closes the upperend of the casing, the valve and balls are introduced into the casing byseparating the two members comprising the same.

After the parts have been assembled and placed within the bottle-neck,the mechanism will render it impractical to refill the bottle. When thebottle is turned to decant its contents, the balls 17 and the valve 16fall away from the valve 15, as shown in Fig. 2, and the contents passthrough the valve-seat into the bore around the valve 1G and the balls17, through the longitudinal passages 18 and escapes through the perfo.

rations 20 in the cap 19 to the mouth of the bottle.

In practice this device has been found to be very eiiicient in itspurpose. It is not only difficult to manipulate the same so as to'refillthe bottle, but the valve mechanism permits a steady and regular flow ofthe liquid without gurgling or splashing. All the parts, except theflexible washer, can be readily made of glass or porcelain, and thedesign is such as to adapt the device to be readily made of suchmaterial. The parts can also be made of aluminum or other non-corrosivemet-al.

Then the bottle is iilled, means are provided to hold thevalve-mechanism closed to prevent leakage during transportation. Turnedinto the cap 19, through one of the perforations 2() therein, is thewooden plug 21 bearing on the upper ball 17. The plug bearing on theupper ball 17 through the intermediate ball, forces the valve 16 againstits seat, and thereby closes the passage through the bore. In the mouthof the bottle outside of the plug 21 is the disk 22 held in place by theusual metal foil 23. The foil Copies of this patent may be obtained forand disk prevent accidental displacement of the plug. For some purposesthe metal foil would be sutiicient protection to the plug, and the diskcould be omitted, as shown in Fig. 3.

Having thus described my invention, what I claim and desire to secure byLetters Pat-- ent is:

1. In valve-mechanism for bottles, a bottle-neck provided with anannular groove in its inner face, a cylindrical valve casing dividedtransversely to form two members abutting at their inner ends andadapted to be seated wit-hin the bottle-neck, collars on the upper andlower ends of the valve casing to lit the interior diameter of thebottle-neck, said collars being spaced apart to form between them anannular space around the valve casing, and a flexible washer clampedbetween the abutting inner ends of the two members of the valve casingadjacent to and normally resting against the lower collar with the edgeof the washer projecting be yond the periphery of such collar, saidwasher operating to fold back into the annular space between the collarswhile the valve casing is being forced into the bottleneck and springinginto the groove in the inner face of the bottle-neck against theadjacent collar on the seating of the valve casing within thebottle-neck.

2. In valve-mechanism for bottles, a bottle-neck, a cylindrical valvecasing to tit the bottle-neck having a longitudinal bore to form apassage through the bottle-neck, said casing having an apertured closureat its upper end and a valve seat in its lower end, a globular valve ofless diameter than the bore of the casing to close said seat inside ofthe bore, balls movable in the bore of the casing above the globularvalve adapted to rest on the valve when the bottle is in an uprightposition and to seat the valve on its seat, said balls having a diameterapproximately the same as the diameter of the bore to close the maincross-area of the bore, said casing comprising upper and lower separablemembers to admit the valve and balls within the casing, the upper memberof the valve casing having in its inner wall a plurality of passagesextending past said balls, and an annular collar on the inner face ofthe upper member of the valve casing flush with the edges of thepassages to register with the upper ball to close said passages when thebottle is in an upright position.

Tn testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
